Automatic resizing all FanArt to 720p?

[strateego]

My windows setup is sluggish on cycling through the FanArt, would resizing the backdrop to 720p from 1080p help improve the speed of the GUI.

How would I go about automatically resizing the fanart to the 720p size on windows?

if your media collection is somewhat organized, MIP has a fanart resize and a compression option that uses image magick

You could also use Image Magick directly from the command line.
for /r %i in (*.jpg) do mogrify -resize 1280x720! "%i"
